I love posts like this. Not that I am going to cry at what your answer will be, but I would love to hear what I do so different than Mark did besides moderating more. Seeing as I talk to Mark all the time (still do, he's my friggin design partner!), we were both pretty much the same when it came to the goals of the site and what we wanted it to be. Hell, he wouldn't have handed it over if that were not the case. He just got to a point where he got tired of dealing with all the a-holes that can make running a site like this fun to enjoy and run, so he stopped working it. It takes a load of work to make everyone happy, and of course you can NEVER make EVERYone happy, so you just do what you think will fall in between somewhere as best as possible.
Let's see your list, I'm always open for (constructive) criticism. (oh boy this should get another 200 posts out of this thread!)
